The following table lists source package names where usage of old config files has been found by grep. There may be false positives. Manual audit is needed.
See the grep results. Look into the actual package sources too.

To help with the effort, please add yourself as Auditor to a few packages and file bugs against them
if they indeed use one or more of the old config files and need to be fixed. The filed bugs should block the tracker bug 881785.
For false positives, just state "false" in the 'Bugzilla' field.
